HOOP-DRlVER.

SPECIFICATION forming part of Letters Patent No. 325,440, dated September lI 1885.

Application filed April 30, 1885. (No model.)

reciprocate vertically by the following de- To a-ZZ whom t m-agz/ concern.:

Be it known that I, GEORGE W. Packen, a citizen of the United States, residing at Rock Falls, in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements in Trussing-Machinos; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains yto make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Myinvention pertains to machines for driving the truss-hoops upon barrels, pails, tubs,

and butter-casks; audit consists, first, in

novel mechanism for pressing such hoops to place, and second, in novel provisions for adjusting such machine to the various sizes of vessels it will be required to operate on.

In the drawings, Figure lis a front elevation of a machine embodying my invention, a partial tulo being shown in position for operation. Fig. 2 is a side elevation exhibiting the method of actuating the cranlchead N, which drives the pitman l?. Fig-3 is a plan of the horizontal head R to which the drivers S T are attached. Fig. 4 is an end view of the cams O and E.

A A are the supporting posts, suitably attached to the base-plate A', and joined at their upper extremity by the cross-beam B and midway by the crossbeam B.

C is a cam hinged at its upper end to the center of the cross-beam B, and hinged at the lower end of iis short side to the toggle D. The other end of the toggle D is hinged to the long end of the cani E. The cams C and E have segmental opposing faces, and one short side, n., and one eccentric or long side,b, and are so relatively placed that when such cams are oscillated laterally, their opposing faces engage throughout their entire length. The opposing faces of the cams C and E are provided with slots d, which receive the toggles D in the oscillation of such cams. The lower end of the caniE is hinged to the top of the vert-ical shaft F, which latter is sleeved in and traverses vertically the center of the central cross-beam B. The cams C and E are oscillated laterally and the shaft F caused to scribed mechanism:

G is a rotating shaft journaled transversely of the machine upon the brackets H,attached, respectively,to the rear of the posts A. The shaft G can be driven from the belt-pulley G', affixed thereon, or in any other suitable manner.

J is a short rotating shaft journaled on one of the brackets H transversely of and directly over the shaft G. Immediately above the shaft G a small gear, K, is loosely placed on the shaft J. This gearK is engaged and continuously rotated by a worin-gear, e, on the shaft G. The outer end of the hub of the gear K is furnished with ratchets f. Adjacently to and outside of the gear K the clutch L is feathered to the shaft J. The inner face of the clutch L is fitted to engage the ratchets f of the gear K, and by means of the short vertical lever M, pivoted on the bracket H directly below the clutch L, and with its upper end forked so as to loosely engage and traverse the annual recess g inthe exterior of such clutch, thelatter is, at will, thrown into and out of engagement with the gear K. Vhen thus engaged the gear K imparts a rotary movement to the shaft J, and to the crank-head N, rigidly seated on the inner end ofthe shaft J. A horizontal transverse pit- "man, P, is pivotall y attached at its outer end to the inner side of the crank-head N, and at its inner end is pivotally attached to the farther or longer end of the cam E and above the pivotal point of the latter. The direction of rotation of the crank head N is from the point of attachment thereto of the pitinan I?, upward and outward, and has the effect of drawing the long end of the cam E under the cam C, and forcing downward the loose vertical shaft F. The toggle D imparts the lateral oscillation of the cam E to the cam O, and thus doubles the downward movement of the shaft F. Such toggle D not only insures the coincident movement of said cams, but also holds the latter in prescribed though varying mutual relation. If preferred,the opposing faces ofthe cams() and E can be cogged or corrugated transversely, so as to engage and actuate each other, in which event the toggle D may be omitted.4 The outer end ofthe pitman P is adj ustably attached to the crank-head N in IOC the radial slot 7L in the latter, and the length of the stroke of such pitman thereby regulated to adjust the movement of the shaft F to suit tubs of various lengths.

B is a horizontal circular head, rigidlyattached at its center to the lower end of the shaft F. To the lower face of the head R are adjustably attached four downwardlyextending equidistant drivers one front one, S, and three side and rear ones, T T T. These drivers S and T are each attached to the head R by means of screw-bolts x, seated, respectively, in radial slots fi in such head, and screwed downward into threaded sockets in the top of such drivers. By this means the drivers may be adj usted to and from the center of the head R, so as to be adapted to tubs of different diameters.

In Fig. l is shown the outline of a tub with the trusshoops thereon in position for being driven. On the inner faces of the drivers S Aand T are formed transverse recesses c,l1av ing upper-abrupt or horizontal walls t0 receive and engage their proper truss hoop. The recesses 7c are adjustable vertically to suit the varying conformation of different tubs by means of clamps V, which forms the abruptor working wall of such recess. The clamps V have horizontal corrugations m on their outer faces, which fit into corresponding corrugations n in the contiguous face of the driver,

and are fastened to the latter by transverse` bolts p. By loosening the bolts p the clamps V may be adj usted vertically, and the recesses K given any desired altitude. The front driver, S, is provided with the hinge lr, so as to be swung out ot' the way in placing or re moving the tub.

NV is the pedestal or base which supports the' tub, and is'providcd with the annular recesses t around its exterior, each of which is adapted to support a tub of a certain diameter. conical form toward its top, so as to be accommodated to tubs of varying diameters and length, it being the fact that tubs of less diameter have also less length. The posts A are attached to the cross-beam B by passing through the ends ofthe latter, and are threaded from a short distance above to a short distance below such beam. Nuts fv and w are placed on the posts A, respectively above and below the beam B, and thus the altitude of the beam B can be adjusted to bring the cams C and E into proper mutual relation and assist in regulating the stroke of the shaft F. A rope, l, is attached to the head R and passed over a pulley, 2, on the beam B,and furnished with a sufficient weight, 3, at its free end, and serves to elevate the head R to position for the succeeding downstroke after the clutch L is disengaged, or such head may be raised by the hand ofthe operator. Each of the recesses t and the base-plate A present a uniform horizontal surfaceto sustain the tub, and the top of the latter is thereby held in line and the top The base NV decreases in diameter in of all the staves in the same plane. is inverted over the base W and rested upon the plate A' or such recess t as will bring it in proper relation to the drivers S and T. The clutch L is then thrown into engagement with gear K and the recesses k forced down upon the truss-hoops until the latter are driven to their proper position, when the clutch Lis disengaged and the tub removed. The hoops when thus driven maintain their rela-tive position, are held horizontal, and can be driven to any desired degree of tightness. But one operation is necessary for each tub.

VhatI claim as my invention, and desire to secure by Letters Patent of the United States, is-
